Structured packings from RVT Process Equipment
In addition to random tower packings and mass transfer trays, structured packings represent a further group of products that are used in the field of mass and heat transfer processes.
RVT Process Equipment GmbH provides a broad range of innovative and conventi-onal structured packings in both metallic and thermoplastic materials for different applications.
Element of structured packing type RMP N 250Y
RPP S 250 Y high performance design of structured packing made of plastics
In some countries outside Europe high performance structured packings may be subject to patent protections of third parties. In case you are interested in countries outside Europe to use these products, do not hesitate to contact us.

The typical application fields for metal structured packings are processes with following operating conditions:
low irrigation densities
high gas loads
low pressure drop requirement
high demand of transfer units
RMP RVT Metal Structured Packings
These operating conditions are common in many vacuum distillation and rectification processes in the chemical and petrochemical industry, as well as in amine scrubbers, C3-, C4-splitters and applications in the field of fine chemicals.
The RMP packings are available in different specific surface areas and corrugation angles as well as in several finishing varieties:
smooth or textured surface
perforated or unperforated
X (60°) or Y (45°) corrugation angles
standard (type N) or high-capacity (type S) corrugation geometry

RPP S 250 Y High performance structured packing made of plastics
So the RPP is mainly used for pro-cesses with corrosive media when the process temperature allows the utilization plastics instead of more expensive metals.

The installation of Hiflow® PLUS in a lying column at the column manufacturer’s site considerably reduces transportation and installation costs at jobsite
In addition to conventional struc tured packings, RVT Process Equipment’s scope of supply includes a lattice structured packing type, which is particularly suitable for applications that require high capacities at even greater liquid loads.
Hiflow® PLUS is a product that combines the advantages of random tower packing and conventional structured packings while reducing the limitations of these two mass transfer components.
The development of Hiflow® PLUS was inspired by the Hiflow® plastic random packing, which has been successfully used in several appli-cations for many years and whose form guarantees outstanding mass transfer efficiency at low specific pressure drops. This extensively proven and tested packing can be easily recognized throughout the lattice structure of the Hiflow® PLUS packing again.
Applicationfields
Typical application fields for random packings are flue gas scrubbers, strippers (e. g. CHC), pre-coolers in air separation plants or amine scrubbers for CO2 separation from flue gases as well as heat recovery scrubbers.

In some of these applications, the gas flows to be treated have attained increasingly large throughput volumes, such as in CCS or SO2 separation processes from flue gases by means of scrubbing. This leads to ever greater column diameters and there -fore to high investment costs. Here, Hiflow® PLUS packing offers distinct advantages as the column diameter and the pressure drop can be reduced without affecting the mass transfer efficiency.
The main performance characteristics and advantages of Hiflow® PLUS are:
lower pressure drop than random tower packing
improved cross flow compared to conventional structured packings
economic production due to reduced raw material requirement
no redistribution required (no wall wipers)
easy installation
installable in a horizontal or vertical column, consequently reducing packing transportation costs and installation time and cost at jobsite
standard liquid distributor as designed for random packing can be used
significantly improved resistance against fouling in comparison to conventional structured packings
For applications with particular operating conditions, RVT Process Equipment offers structured packings made of highly resistant plastics such as PVDF and PTFE. Typical application fields are HCI absorbers, SO2 absorbers with operating temperatures up to a maximum of 130 °C.
Ceramic structured packings are mainly used for even higher temperatures and corrosive process conditions. RVT Process Equipment manufactures conventional ceramic structured packings in both X (60°) and Y (45°) corrugation angles as well as with specific surface areas from 125 to 450 m2/m3.
